Indicative Re-jetting matrix

conradvr · October 01, 2003, 10:00:37 PM

Ok, I have spent hours now ready all the posts about jetting the carbs. I thought that it would be great to have a rejetting matrix to assist others in determining a starting point/indicative guide. Please those that have experience and the 'know' correct and add (also please add new combinations).

Air Filter: (s) - Stock Air Box, (p) - Pod replacement for Stock Air Box

Exhaust: Perf - aftermarket performance pipe

Kit: Fac1 - Factory Pro Stage 1, Dyn1 - Dyno tune Stage 1, K&N1 - K&N Stage 1, Fac3 - Factory Pro Stage 3, Dyn3 - Dyno tune Stage 3, K&N3 - K&N Stage 3

Damn it - all the formatting got lost when I posted this message (removed the white spaces). Please let me tidy up the table before you posts replies.

Thanks
Conrad

this is great! i was looking for something like this earlier today, since i know nothing about carbs. thanks!

conradvr · October 01, 2003, 10:24:00 PM

ok - reformatted using lotsa dots - please those gurus out there add and edit to your hearts content.

Cheers

Someone should archive and post that.
We all know, I am to lazy.( I last updated my page some time, last year

)
Any energy, Pablo, Kerry, Jeff, anybody?

miket · October 02, 2003, 01:40:55 AM

That's an excellent idea. Perhaps one more column with # of people that have each combination would be useful.
Additionally, there should be a separate table for >=01.

If you want, I can host it on my web site in with my rejetting page.

BTW, I have Uni in the box, V&H, 40 pilots, 127.5 main, 2 washers, 3 turns out. Seems to work ok for me, maybe a tad too rich.

The Buddha · October 02, 2003, 08:00:30 AM

Well K&N in airbox is what 127.5 is really ideal for. Find out where its rich and maybe just turn that circuit leaner a little. However you have to try the jetting on the coldest day of the year...Basically in NC...the last few days would be about right for that...

.
Cool.

Good Job!!

Yeah, in fact, it is running like a champ lately

I, on the other hand, was freezing coming back tonight! It must have been in the fifties!

jiggersplat · October 03, 2003, 09:13:19 PM

anyone got the scoop on just a k&n pod, no exhaust?

dan

That's my set up right now.

K&N Pod, stock exhaust: 40 pilots, 2.5 turns out, 2 washers (~1.2mm), 147.5 mains. I think others have used smaller mains - more like 140. I started w/ 145's and my bike runs better w/ the 147.5's. Plugs look just about right - definately not rich. I rode Pkaaso's bike the other day (K&N, slip-on, 150 mains) and it felt comparable - maybe just a tiny bit more pull at the top end. So I think my mains are just right. My low-mid throttle seems maybe a little bit soft, but not sure if it's abnormally so.

Rashad · October 05, 2003, 04:36:04 PM

Im running:

Vance and Hines Fully system, K&N pods, 40 pilots, 2 washers(for 1mm total) 150 Mains... 99 motor on a 91 gs..lol

Awesome idea!!!

Oh yeah, Bob's ignition advancer is on there as well!

Flash · October 06, 2003, 12:39:37 AM

NICE JOB conradvr

I always thought about doing this, but you beat me to it.

I have the #1 setup for my '96 GS.

Now all we need is Suzuki part #s (Did I just open up a can of worms or what!?!?!?!?)

#4 washer (hardware store)
#40 Pilot jet (Suzuki part# 09492-40014) - 1 Mikuni #40 non-bleeder
#125 Main jet (Suzuki part#

??) - not sure, but this one is easier to get without problems from the Suzuki dealer

The Buddha · October 06, 2003, 09:05:06 AM

Yea me too...
Was running 150/40/3 turns/2 washers with K&N clamp on filters and slip on V&H can on stock headers. Works perfect on my 89.
I now have 37.5 pilots in it... Has 3.5 turns on screws, and has that annoying spot right at take off that has a distinct raspy sound and some weakness in power... 40's are on order...
Cool.
Srinath.
